Abstract (en)
A process is disclosed for preparing a polymer/starch composite. The process involves forming the polymer in the presence of starch, an organometallic cocatalyst, and a particulate olefin polymerization catalyst. Also there is disclosed a process for improving the activity of a particulate olefin polymerization catalyst by the employment of a suitable amount of starch during the polymerization.
